The invention discloses a multi-power flow-controllable phase-change boosting emitter which comprises an electromagnetic valve, a body pipe and a ball head sleeve, wherein the electromagnetic valve is used as a part of a Laval nozzle; the ball head sleeve is connected to the front end of the body tube; the laval nozzle contraction section, the electromagnetic valve and the laval nozzle expansion section are sequentially connected to form a laval nozzle; the contraction section of the Laval nozzle is connected to the rear end of the barrel; a plurality of high-pressure chambers are arranged on the barrel and filled with liquid carbon dioxide; a heating device is arranged on the high-pressure chamber; the barrel serves as a low-pressure chamber; a diaphragm assembly is arranged on the high-pressure chamber; the high-pressure chambers and the low-pressure chambers are provided with temperature sensors and pressure sensors so as to control the starting time of the heating devices on the different high-pressure chambers, sequential heating of the high-pressure chambers is achieved, and the pressure of the low-pressure chambers is increased by controlling sequential heating of the other high-pressure chambers. The problems of large overload and impact damage of high-pressure gas to the unmanned aerial vehicle are solved.

    本发明专利公开了一种多动力流量可控式相变助推发射器,包括作为拉瓦尔喷管一部分的电磁阀、身管、球头套;球头套连接在身管前端;拉瓦尔喷管收缩段、电磁阀、拉瓦尔喷管扩张段依次连接形成一个拉瓦尔喷管;拉瓦尔喷管收缩段连接在身管后端;身管上设有多个高压室,高压室内填充液态二氧化碳;高压室上设有加热装置;身管作为低压室;高压室上设有膜片组件;高压室和低压室均设有温度传感器和压力传感器,以控制不同高压室上加热装置的启动时间,实现高压室的依次加热,通过控制其余高压室时序加热,提高低压室压力。解决了高压气体对无人机的大过载、冲击损伤的问题。
